largefiles: restore standins from non branch-tip parent at rollback correctly Before this patch, "hg rollback" can't restore standins correclty, if: - old parent of the working directory is rollback-ed, and - new parent of the working directory is not branch-tip "overriderollback" uses "merge.update" as a kind of "revert" utility to restore only standins with "node=None", and this makes "merge.update" choose "branch-tip" revision as the updating target unexpectedly. Then, "merge.update" restores standins from the branch-tip revision regardless of the parent of the working directory after rollback and this may cause unexpected behavior. This patch invokes "merge.update" with "node='.'" to restore standins from the parent revision of the working directory. In fact, this "merge.update" invocation will be replaced in the subsequent patch to fix another problem, but this change is usefull to inform reason why such complicated case should be tested.

largefiles: omit restoring standins if working parent is not rollbacked For efficiency, this patch omits restoring standins and updating lfdirstate, if the parent of the working directory is not rollbacked. This patch adds the test not to confirm whether restoring is skipped or not, but to detect unexpected regression in the future: it is difficult to distinguish between skipping and perfectly restoring.

histedit: drop duplicate line extracting keep option

import: avoid editor invocation when importing with "--exact" for exact-ness Before this patch, external editor is invoked when imported patch has no commit message, even if "--exact" is specified. Then, exact-ness is broken, because empty commit message causes failure of committing. This patch avoids editor invocation at importing with "--exact" for exact-ness, because commit message in the patch should be kept as it is in such case, even if it is empty.

import: disallow meaningless combination of "--exact" and "--edit" Before this patch, "hg import" allows combination of "--exact" and "--edit", even though editing commit message breaks exact-ness. This patch disallows meaningless combination of "--exact" and "--edit".
